Northern Coast Timber Company was in business ca. 1907 to ca. 1915, with logging operations at Kangley and then at Maple Valley.

Kangley is a community on a small tributary of the Green River, eleven miles northeast of Issaquah in southwest King County. It was named by the Northern Pacific Railway for John Kangley, general manager of Northern Pacific Coal Company in 1889. Alternate names were Kangley Junction and Durham Junction. A railroad depot was built in 1906 and abandoned in 1920.

Maple Valley is a community ten miles south of Renton near the Cedar River in central King County. In 1879, the town was founded by George W. Ames of Seattle, and platted in 1890. In 1888, the name was chosen by George Ames, when a post office was established. It was not for the abundant western maple trees in the area, but for the Maple family (Jacob and Samuel), who settled on the Duwamish River before the Denny party arrived at Alki Point.
